MACHINE FOR PAGING BOOKS, &o.

Specification of Letters Patent No. 16,207, dated December 9, 1856.

To all whom it may concern:

Be it known that I, R. L. I-Liwns, of lVorcester, in the county of orcester and State of ll/Iassachusetts, have invented certain Improvements in Machines for Paging Books and Numbering Tickets, Bank-Notes, and other Similar Articles, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part of this specification, in which- Figure l is a plan. Fig. 2 a vertical section upon the line A, A, of Fig. l. Figs. 3, A and 5 details which will be referred to hereafter.

To enable others skilled in the art to understand my invention I will proceed to describe the mann-er in which I have carried it out; giving first the general construction and operation of my machine and then the details which form the subject of my invention.

The operating parts of the machine are carried by the bed or frame B which may be constructed of cast iron or other suitable material; to this bed is also secured the table C which holds the book or other arti cle to be numbered. The numbering wheels D are constructed and operated in a manner similar to those described in Letters Patent granted to IV. C. Demain on the 21st of August 1855. One of these wheels together with the spring bolt by which it is held stationary while the impression of the type is being made, is shown in Fig. 5. As their construct-ion and operation form no part of my present invention, they need not be further described. The lever E to which the numbering wheels are attached is pivoted to the frame at b and is connected with the treadle F, by the link G in such a manner that when the treadle is depressed the numbering wheels are brought down upon the platen H; the spring K serving to keep the parts in the position represented in Fig. 2. f and g are adjustable guides which serve to regulate the position ofthe page or other article to be numbered. S is an adjustable stop against which the arm E strikes in its descent, to prevent a more violent blow than is necessary being given upon the plate II.

I is a lever pivoted to the shaft upon which the numbering wheels turn, and which carries the pawl L which actuates them; this lever is allowed to move a sufiicient distance to carry the numbering wheels one notch or two notch-es at a time as in other machines of this description. YVhen it is desired to number consecutively, the range of motion of the lever I is limited by the pin M, when it is desired to move the wheel two notches at a time in order to print every other number, as in paging books, the pin M is withdrawn and a greater range of motion is allowed to the pawl; the lever I is retracted and retained in the position seen in the drawings by the spring O.

The pawl L is thrown forward for the purpose of turning the numbering wheels as the lever E descends, in the following manner: P is a dog attached to the bed piece, against which the pin m projecting from the lever I strikes as the numbering wheels descend, by which means the pawl L is caused to operate the ratchet wheel R attached to the first numbering wheel.

It is evident that a much greater force will be required to start the wheels than will be necessary to keep up their motion after the spring bolts 7c which hold the wheels stationary while an impression is made are once withdrawn from their notches. This starting of the wheels is effected by the pin m which operates with a long leverage, and easily effects the release of the wheels from their spring bolts. So soon as this is effected, the projecting arm 7L of the lever I strikes against the dog P and accomplishes the continued motion of the wheel.

In lieu of inking the types previous to each impression I have adopted the following plan: S is a silk ribbon which is charged with the ink or other printing material, which is wound upon the spools T and U (seen dotted in Fig. 2) and passes around the numbering wheels. As the numbering Vwheels descend, the ribbon is forced down upon the paper and thus the ink with which it is charged is pressed out of it on to the surface of the paper by the type, an accurate impression of which is produced. The ribbon is fed slightly forward after each impression, in order to bring a fresh surface beneath t-he types, in the following manner. The spools T and U are carried by the standards IV secured to the lever Fi-a, c are ratchet wheels attached to the spools; l is a feeding pawl that is pivoted to the lever n which is itself pivoted to the standard W and rests upon the top of the stationary dog Z againstI which it is caused to bear by the spring X as the numbering Wheels rise after an impression, the lever a is raised by the dog Z and thus the spools are set in motion. r is a retaining paWl Which prevents the retraction of the ratchet Wheel a and spool T. Vhen the ribbon is nearly all fed ont-o the spool T the paWls r and fl are thrown over into the position seen in red, and it is fed back again onto the spool V, it may thus be fed back and forth a number of times, before it again requires to be charged with ink. IVhen an inking apparatus of this description is employed, a much greater pressure is required to give the impression than Where the ink is put directly upon the face of the type; this precludes t-he employment of a platen with a soft or elastic surface, as the pressure required would cause the typ-es to cut through the paper. A platen with a metallic surface having a single thickness of paper over it is therefore employed, and in order that such a platen may accommodate itself to the surface of the types, should they fail to fall in exactly the same plane, the plan represented in Figs. 3 and t is adopted Fig. 3 is a plan of the platen;Fig.4 asection upon the line a of Fig. 3; the platen is composed of separate metallic blocks t', z', there being one for each individual Itype; these blocks rest upon india rubber or other suitable spring which allows them to yield slightly, independently of each other, and thus to accommodate themselves to the face of the type as required.

That I claim as my invention and desire to secure by Letters Patent isl. The general construction and arrangement of the machine, that is to say pivoting the lever E Which carries the numbering Wheels, to the framework and operating the Wheels by means of the dog P, the arm i and pin my, in the manner substantially as herein set forth.

2. In combination with the method herein described of giving the impression by means of the revolving ribbon S, I claim giving to each type an independent bed or platen, and supporting the platens upon springs in the manner and for the purpose set fort-h.
